does this server have more than 1 network interface - where exactly are you going to sync too. Do you have more than 1 AD dns server in your network. Do you have more than 1 DC? Where are all the roles located?

It has 4, they are all disabled except for the one in use (since I do not have need for them). 1 AD DNS server only, and 1 DC only. Roles are all on the central/primary DC.
